Grey-headed Junco 379 
feathers of the latter white, the third pair partly white and dusky ; 
iris brown, bill pale pinkish in life, dusky at tip, legs horn-brown. 
Length 6-10; wing 3-35; tail 3-05; culmen -40; tarsus -75. 
The female resembles the male, but is smaller—wing about 3.0; 
a@ young bird is dull greyish-white on the head and neck and below, 
while the back is a duller shade of the adult chestnut ; the head, back, 
throat and breast are all streaked with blackish ; the streaking is lost 
by the first winter, when it is essentially like the adult. 
Distribution. Breeding in the mountains of southern Wyoming, 
south through Colorado, Utah and Nevada to northern New Mexico, 
wintering in lower levels in the mountains and in the foothills, and 
south to northern Mexico. 
In Colorado the Grey-headed Junco is a resident, breeding every- 
where in the mountains from about 7,500 feet (Magnolia, Boulder co., 
Sprague apud Cooke, 97) to timber line (Trippe). It winters in sheltered 
spots at lower elevations in the mountains, but is chiefly met with 
in the plains on the spring migration; nearly all Mr. Aiken’s series 
from near Colorado Springs were obtained in March and April. 
The following are some breeding records : Columbine Lake, Grand co., 
9,000 feet (Rockwell), Estes Park (McGregor), Boulder co., 9,500 to 
10,000 feet (D. Gale); near Hancock (Stone); Pikes Peak and Mount 
Fisher, near Trinidad (Aiken), Wet Mountains (Lowe); Mesa co. 
(Rockwell), San Juan co. (Drew), while it has been taken by Aiken 
on the plains at Resolis in Elbert co. (Drew), fifty miles from the moun- 
tains, as late as May 25th, and at Fort Lyon by Captain Thorne. 
Habits.—The Grey-headed Junco is not commonly 
seen near Colorado Springs with flocks of the other 
species during winter ; it seems to keep by itself and to 
remain at somewhat higher elevations, but in March and 
April it becomes abundant, arriving from the south and 
gradually moving up into the mountains to nest. Aiken 
(75) was the first to describe the nest and eggs of this 
species, but many observers have done so since. Fresh 
eggs are to be met with from the end of May till late 
in July, and there seems to be no reasonable doubt that 
two or three broods are raised in the season. Gale 
found a great many nests near Gold Hill, and the fol- 
lowing is taken from his notes on the subject: “‘ Nests 
on the ground, and is fond of selecting sheltered places 
such as the side of a hill or bank ; the nest is well set in
